You should really get on Digi-Key or other distributor who
has a good web site and see if you can find a new model that
fits the same mounting hole and PC board pattern. Even if
C&K obsoleted the exact model, they very likely still make a
compatible part. Digi-Key shows 408 items when I search on
"C&K 7101". Some of those REALLY look like stuff I remember
in DEC equipment.
